I have a few modems laying around and noticed, (especially on the
lower cost ones), that there isn't even a transformer on the PCB for
interfacing to telphone line.
All of them are using DAA chips but I would assume that a transformer
would almost be mandatory in getting part 68? approval.
Guess not though?
I have one modem here, a motorola, that just goes straight into the
phone line from the DAA chip.
